title: Carbocupration-functionalization of arynes: rapid access to variably ortho-substituted ((E)-3-phenylprop-1-enyl)silanes.
abstract: A consecutive three-component coupling reaction involving a lithium di[3-(prop-1-enyltrimethylsilyl)]cuprate, variably substituted ortho-arynes, and a selection of common electrophiles is described. The method affords readily functionalized homobenzylic vinylsilanes with exceptional E-diastereoselectivity and allows for in situ incorporation of carbon- or heteroatom-based electrophiles into the arene.
